Even if it is by natural process, there is very little doubt in the scientific community that global warming is real and is occurring. I don't think you'll find many researches who will say that global warming is not occurring. The real debate lies in how much of an influence humans are having in the warming, and how much of the warming is occurring naturally. IMO, it makes sense to assume that humans have some impact given the tons, and tons, and tons, and tons, and tons, and tons of greenhouse gases spewed into the atmosphere every year for the past 80 years. Some simple chemistry experiments can show that some gases are indeed greenhouse gases, with a property to absorb and/or re-emit energy / radiation. Now, there may be a natural tendency for the earth to be warming, but the extremely rapid rise in the rate of warming seen in the past 100 years coincides nicely with the rise of industrialism and the rate at which CO2 and other greenhouse gases have risen. I guess I'm getting into the whole global warming debate again (LOL we've had how many on ST in the past year? :lol: ), so I'll stop.
I am reminded of Doswell's recent essay about "damage porn" LOL.
